In spite of widespread interest in datacenter networks, little has been published that reveals the nature of their traffic, or the problems that arise in practice. This paper is a first attempt to capture both the macroscopic patterns - which servers talk to which others, when and for what reasons - as well as the microscopic characteristics - flow durations, inter-arrival times, and like statistics - that should provide a useful guide for datacenter network designers. These statistics appear more regular and better behaved than counter parts from ISP networks (e.g., "Elephant" flows only last about one second).
